• Cat.No.: Protein A-2938S
• Product Overview: Protein A is A cell wall protein secreted by Staphylococcus aureus, also known as Staphylococcal Protein A(SPA), Natural protein A is mainly composed of three functional regions: signal peptide, 5 antibody binding domains and cell wall peptidoglycan binding domains. The most studied and applied region is the 5 antibody binding domains with antibody binding functions. Recombinant protein A was genetically engineered and expressed in the antibody-binding domain (E-D-A-B-C) of natural protein A, which has the complete antibody-binding function of natural protein A.
